Vita. Includes bibliographical references. Many computer aided design (CAD) software packages focus on detailed design and not on early stage, conceptual design. The ability to conceptualize and sketch early versions of a product solution is currently limited to paper and pencil or to inadequate computer-aided industrial design programs (CAID) that focus mainly on surface design, not product design. Working on a design as a group also poses problems since the team can be geographically distributed. In an attempt to address the current inadequacies of CAD systems for distributed conceptual design, my thesis proposes a vision for a new CAD program, DC-CAD. This vision anticipates network-orientated conceptual design, and encompasses capabilities for multiple users to collaborate simultaneously on design, compare & evaluate concept sketches, comment on designs and merge changes from other designers, transfer data to detailed design CAD programs, and record concept changes over time. MIT's Product Engineering Class (2.009) was used as the basis for conceiving the software system. By analyzing design challenges that arose during the course, new software features are suggested to mitigate such problems. (cont.) The end result is a clear vision for a new program, DC-CAD, and a storyboard example of how it could be used in a futuristic 2.009 setting. The thesis closes with recommendations on how to pursue the implementation and realization of such a CAD system. by Mark D. Egan.
